A newly released study finds that young people are increasingly exposed to e-cigarette, or e-cig, advertising.

Between 2011 and 2013, exposure to e-cig television ads increased 256 percent for adolescents ages 12 to 17, according to a new study in the academic journal Pediatrics. In the same time period, e-cig ad exposure increased 321 percent among young adults ages 18 to 24.

Television and radio advertising for cigarettes has been banned in the United States since the early 1970s, but the law doesn’t cover e-cigarettes, which contain nicotine but not tobacco.

Indiana legislators last year passed a bill banning minors from purchasing e-cigarettes, but several states have no age regulation for the product.

According to the study, e-cigarette use and awareness will likely increase among younger people if these advertising trends continue.

What do you think? Should more be done to limit youth exposure to e-cigarette advertising?
